# Electric currents

How does the  type of circuit affect the strand of Christmas lights with a burned out bulb.

The iv is the parallel circuit and the series circuit.. The Dv is if the light will light up or not.

If the Christmas lights are arranged in a parallel circuit then when 1 bulb burns out the other bulbs will light up.

I observed that all the lights are lit  when in a parallel circuit and no bulbs are burned out.

I observed that the two lights stay lit when I removed one of the bulbs in a parallel circuit.

If the Christmas lights are arranged in a series circuit then when one bulb bursts the other bulbs will not light up.

In a series circuit all the light aligned are lit up.

I observed that the other bulbs did not stay lit when I removed one of the bulbs.

In a parallel circuit with zero bulbs removed all three lights are lit. When one bulb is removed two lights stay lit.

In a series circuit with zero bulbs removed all three lights are lit up. With one bulb removed zero lights are lit.

Mrs. Thayer is awesome.
